I'm not sure if this is the right place to ask, but... I've been playing with GeoTools 8.0M-1, in particular trying to read some GeoTiffs. Each time, it crashes with the error No code "EPSG:2193" from authority "EPSG" found for object of type "EngineeringCRS". The GeoTiff I'm reading is an NZGD2000 map. A Google for NZGD2000 and 2193 finds http://resources.esri.com/help/900/arcgisexplorer/sdk/html/612c4dad-84c2-7ec5-2e23-7db2bdfecc7d.htm ?
How can I get that information into the GeoTools, so that it will carry on and read the image via the GeoTiffReader class?
